If f(4a) = 80, then the value of "a" is 4.2
<em><u>Solution:</u></em>
Given that cost for the olive oil used to fill the containers on the tables in an Italian restaurant is given by the function:
f(x) = 5x – 4
where "x" represents the number of quarts of olive oil
f(x) represents the quarts of oil used
To find: value of "a" when f(4a) = 80
Substitute x = 4a in given function
f(4a) = 5(4a) - 4
80 = 20a - 4
20a = 84
10a = 42
a = 4.2
Thus the value of "a" is 4.2
The answer that I got was y=105
Hope this helps!
Answer:
1/2 is less than
Step-by-step explanation: 1/2 is only 50% while 4/5 is 80%
Answer:
A and B. See explanation
C. x=4
Step-by-step explanation:
A: Consider two functions and The point of intersection of the graphs of these two functions is the solution of the system
When you are solving this system, you have to equate the right sides of these equations and get So, the x-coordinate of the point of intersection is the solution of the equation
B.
C. Graphically, graphs intersect at point (4,16), so x=4 is the solution of the equation
